There are actually 3 current usages of digits in the (English)
normative character names:
1. "9" appears in the names for the directional quote marks, U+201A,
U+201B, U+201E, U+201F. Those constitute the original exception for
use of a digit to represent a shape, as in "LOW-9" and "HIGH-9".
(This was, in my opinion, simply a name hack, and may originally
have been motivated as a kind of name annotation to prevent
translators of character standards from translating the "9" into
2. Digits representing the UCS code point occur in both the unified CJK
characters and in the compatibility CJK characters:
CJK UNIFIED IDEOGRAPH-4E00, etc., etc.
CJK COMPATIBILITY IDEOGRAPH-F938, etc., etc.
3. Digits representing the dot positions occur in the Braille pattern
U+28FB BRAILLE PATTERN DOTS-1245678, etc., etc.
And one more usage in the character names accepted in ISO/IEC 10646-2:
4. In the Mathematical Alphanumeric Symbols, for math styled digits:
U-0001D7CF MATHEMATICAL BOLD DIGIT 1, etc., etc.
The latter three cases have broken the "only to represent their shapes"
exception wide open. And I think it is only a matter of time until
WG2 also accepts the convention of using numeric catalog values for the
character entities of some historic scripts, where those catalog
values would be more useful to the users of the standard than some
arbitrarily concocted alpha-only names that avoid the use of digits
in the name.
